Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, the utility model provides a novel fire control signal butterfly valve, including valve body 1, valve body 1's inside is fixed and is equipped with limiting plate 6, and limiting plate 6 is the plectane, and two fan-shaped openings of symmetry are seted up to one side of limiting plate 6, and one side laminating of limiting plate 6 has two butterfly plates 7, and butterfly plate 7 is the fan-shaped plate and corresponding with the fan-shaped opening of limiting plate 6, and the top of two butterfly plates 7 is the long pivot 8 of fixedly connected with and short pivot 9 respectively.

Then, the top ends of the long rotating shaft 8 and the short rotating shaft 9 are both provided with a first meshing structure 11, the long rotating shaft 8 is in meshing connection with the short rotating shaft 9 through the first meshing structure 11, the two first meshing structures 11 are respectively in meshing connection with corresponding second meshing structures 12, the two second meshing structures 12 are respectively and fixedly arranged at one end of the long driving rod 13 and one end of the short driving rod 14, and the long driving rod 13 is in meshing connection with the short driving rod 14 through the second meshing structures 12.

And then the other end of the long driving rod 13 is fixedly connected with one end of the rotating rod 4, the other end of the rotating rod 4 is fixedly connected with a manual rotating wheel 18, the middle part of the short driving rod 14 is fixedly provided with internal teeth, the internal teeth are in meshing connection with external teeth, the external teeth are fixedly arranged on the inner wall of one side of the independent fixture block 15, the position of the independent fixture block 15 corresponds to that of the sealing door 5, the other end of the short driving rod 14 is connected with a bearing 16 in an inserting way, and the short driving rod 14 is fixedly connected with a pointer arranged inside a gauge head.

Last the fixed axle sleeve 2 that is equipped with in middle part on 1 top of valve body, the fixed plate 10 that is equipped with of inner wall of axle sleeve 2, fixed plate 10 all alternates with the middle part of long pivot 8 and the middle part of short pivot 9 and be connected, and the top fixedly connected with transmission cover 3 of axle sleeve 2, the top of 3 one sides of transmission cover alternate and are connected with bull stick 4, and sealing door 5 has been seted up to the avris of transmission cover 3.

When the novel fire-fighting signal butterfly valve is used, firstly, the butterfly valve is installed, then the manual rotating wheel 18 is rotated, the manual rotating wheel 18 drives the rotating rod 4 to rotate, the rotating rod 4 drives the long driving rod 13 to rotate, then the long driving rod 13 drives the long rotating shaft 8 to rotate through the first meshing structure 11, because the long rotating shaft 8 is meshed with the short rotating shaft 9, the two butterfly plates 7 can be driven to synchronously open and close, because the butterfly plates 7 are positioned on one side of the limiting plate 6 and are jointed with the limiting plate 6, only one-way opening and closing can be realized, the water flow pressure is small, the butterfly plates can not have the function of opening, because the long driving rod 13 is meshed with the short driving rod 14, when the long driving rod 13 rotates, the short driving rod 14 can be driven to synchronously rotate, thereby the pointer of the meter head 17 rotates, the opening and closing degree of the butterfly valve can be conveniently known, the size of free control water flow, after the butterfly plates 7 are rotated to the desired position, the sealing door 5 is opened, the independent clamping block 15 is clamped with the middle part of the short transmission rod 14, the short transmission rod 14 can be fixed, so that the butterfly plate 7, the rotating rod 4 and the manual rotating wheel 18 are fixed, and finally the sealing door 5 is closed, so that the situation that the butterfly valve is closed by misoperation and the use in case of sudden fire is delayed can be prevented.
